Experimental Study On The Soil Erosion Based On Artificial Simulation Of Rainfall And Soil Erosion Forecast Model Of North Brae In Yi Ning

The soil erosion is the direct cause of the water and soil loss, globally and nationally the process of soil erosion has become a serious issue. In the past 30 years, many works have been done on soil erosion mechanism of sloping surface by research scientists in the Loess Plateau. But certain achievement has not gained in Xingjiang Province. In this paper, taking rain erosion of the frequent disasters in Yining Area as an example,based on Remote sensing and rainfall simulator methods, Firstly systematic, quantitative study of the main effects of soil erosion andthe impact of changes in the mechanism, explored the rain erosion get rain erosion prediction model, the work done aims to the Xinjiang soil erosion on some potential for exploration. It is urgent to study and find a effective way to control soil erosion.Artificial simulation of rainfall device was successfully manufactured by our laboratory research team, The device includes sprayer, bracket, water supply and power supply. Rainfall intensity, rainfall uniformity and raindrop descent terminal velocity is conform nature raindrop. artificial simulation of rainfall was adopted to study the rainfall erosion in the North Brae in Yi Ning,Be of different cropping,different rainfall rate and different slope degree to the soil erosion experimentation, Through experimentation study and theory analyze, The erosion produces the sand process in different slopes ,rainfall intensity and slope gradient. The research development of soil erosion models at home and abroad was systematically analyzed. R of rainfall erosive and K value of soil readability have get,Then distribution of rainfall erosive was researched. The other factors of soil erosion model were quantitatively studied.To get a simple and applied evaluation method, this paper combined theory of quantification with soi1 erosion forecast for the first time. As a result,application range of quantification theory has been developed and direct a new way for the soi1 erosion forecast. The result of test indicated that it is feasible to solve this problem with theory of quantification, and it can overcome the shortage of artificial scores, enhance the accuracy and reliability of evaluation for soi1 erosion forecast.The research result could help the decision making for further water and soil conservation work ,and it also offers reference for monitoring. evaluating and forecasting soil erosion.,which gives some reference and advice for making water and soil conservation project and preventing and curing water and soil loss in other areas of Xingjiang Province.
